Does anybody have a clue where to get information and/or parts
for a Skil model 732 RotoHammer?

It uses a 3/4" hex shank chisel with a 5/8" hex shank to drive a
drill and a roughly half-inch tail to engage the hammer.

Some time ago I found an SDS+ adapter with a hex shank that
sort-of works, but the shank is 13 mm so it's rather sloppy.

I drew a blank a few years ago and am hoping something new might
have turned up. One YouTube video suggests it was made by Bosch,
which I'm following up presently. I phoned Skil, they claim it
was made by Skil and they have no further information.

It runs but is somewhat tempermental, I think there might
be some trick to lubricant selection. It came with grease
in the crankcase, the YouTube video comments suggest it
requires some sort of oil.

Thanks for reading,

I always take YouTube comments with a grain of salt. Sometimes they are
very useful, and sometimes people have some vague relation to the topic
and feel the need to say something even if its wrong. They can
sometimes be a different point to start looking for information in
either case.

Found some bits here:
===
Carbide Tipped Heavy Duty 9/16" Hex Shank Masonry Hammer Drills,
commonly classified as the Skil 728 Hex Shank, are designed to fit
the following 9/16" hex drive rotary hammers: Skil 628,728, 731, 731,
732, 1760 Milwaukee 5325, 5326
Black and Decker 5048
Miller Falls SP 499K
Rockwell 602, 1602, 606, 616
(Complete Global Reference on Pages 162-163)
9/16" Hex shank rotary hammer drills have 6 flats on the shank to
ensure a positive drive action and a fl at bottom on the end of the
shank for tough hammering of aggregate. They are used for drilling
holes from 3/8" to 1-1/2" in concrete, masonry and stone.

Page 5 in this old catalog for it claims it uses grease. https://ia802805.us.archive.org/15/items/SkilCatalogI1131973/Skil%20Catalog%20I-113%201973.pdf
No luck finding a manual. I'll search some more when I get a chance if
you REALLY need more info than thisEfOeN+A

I did find those guys in my initial search. As it happens
the machine came with a few bits, not in great shape but
usable. I bought it for $50 somewhat on a whim, intending
to drill some anchor holes in concrete. It's very much a
handful to control and heavy to boot, so it's not seen
much use. Looks like its previous life was hard, however.

Page 5 in this old catalog for it claims it uses grease.

That's considerable help as it is. I'll not try using oil!
One mystery remaining is an adjustment below the motor
on the gearcase may "T" and "L" with opposing direction
arrows. There's a matching Torx-like key among the items
in the kit. Perhaps something to do with the "clutch"?
Not clear on what the clutch is for, unless it's to
prevent wrapping the operator up if the bit jams....

Thanks _very_ much for writing!

I would guess it is for the Clutch too. Read mention of the Clutch and
a key supplied in the original kit for adjusting it on the catalog
page...
Many, many years ago I ran a Rockwell a few times that looked a lot
like that Skil. Was drilling 2-3 inch holes through a poured concrete
wall with a core bit. Once the bit was deep in the hole it was
quite easy to tilt the machine slightly and cause the bit to bind up.
The clutch would allow it to slip, stop turning while you adjusted the
angle back to where it wouldn't slip and keep drilling. Can only
imagine how nasty that could be without a clutch allowing some
slippageEfy4N+A
